Specifications include, but are not limited to: The City has experienced odor control complaints at the Southwest Wastewater Treatment Plant (SWWWTP) and along the plant’s main collection system. The City performed a multiphase odor control demonstration program in 2006 to determine the best method to control odors at the plant. The addition of iron and hydrogen peroxide in the collection system proved to be an effective method of controlling odors. Attachment A provides a schematic of the system and recommended feed locations. The intent of the Invitation for Bid and the resulting contract is to obtain a Contractor who shall provide Odor Control Services for the City of Springfield, MO, to control odors within the collection system at select locations and at the primary clarifiers located at the Southwest Wastewater Treatment Plant. The program shall utilize PRI-SC® technology as patented by USP Technologies (formerly U.S. Peroxide). This system shall include the addition of iron salts at the Lone Pine lift station which feeds into the James River force main and the addition of hydrogen peroxide at the influent junction box located at the Southwest Wastewater Treatment Plant to regenerate spent iron. The regenerated iron and hydrogen peroxide will mix with two other influent flows (South Creek Interceptor and Roundtree force main) at the influent junction box. In addition, the Wilson Creek gravity interceptor and the Roundtree force main will be treated with hydrogen peroxide alone. Iron will also be added at the City’s Department of Environmental Services, Sewer Maintenance Facility to control H2S in the South Creek line.
